GEORGE H. FORSYTH, OF CHICAGO, ILLINOIS,

cAR-wmnow cons'rairc'rron Application filed May 17, 1915. Serial No.28,546.

To all whom it may concern:

Be it known that I, GEORGE H. FoRsr'rH,

a citizen of the United States, residing at Chicago, the county of Cookand State".

of Illinois, have invented certain new and useful Improvements inCar-Window Construction, of-which the following is afspecification. i

The purpose of this invention is to provide a window frame constructioncomprising a bottom sill member or window stool preferably providedwitha suitable incline and step for the sash, and having the ends ofsaid sill member turned upwardly and extending, if desired, clear up toand preferably beneath the letter-board of the car, the latter alsobeing preferably fastened to the top ends of the side members andserving as a tie 'member for the'latter. Either the lower margin of theletter-board itself can be turned inwardly at'the Window openings toprovide suitable top finish, or a separate top finish cross member canbe provided be- 7 tween side frame members and a straight letter-boardemployed, the said finish mem-' ber lying preferably within the lowermargin of the letter-board and forming in effect a part thereof. I Thisdesign of window frame is much cheaper of manufacture than where theframe ispressed up out of a sheet of metal into a box-like structure,the said pressing then having to be blanked out'to form the windowopening as wellas the inwardly turned flange at the top to allow for theupward movement of the sash. I

I show several modifications of the above window frame structure,including, as stated, a separate finish member for the top of the frame;and this finish member can either extend to the side members of the Iing this window frame, inuwhich the membet to be formed into the windowframe is an anglesection. The latterv is placedcentrallyon the top of adie block whose width Specification of Letters Patent. Patented is'thatof the desired window frame, and

s lesme whose top surface is provided with ,the proper formation toproduce the incline'for v V the sill and the step for the sash;The'pu-nch" constituting the upper die member "comprises a block havinga'preferably shallow depression, whose cross wall is likewise providedwith proper formation to assist the lower die to produce the properincline and step for the sill. Thesedie members are rounded off so thatall edges and endsand I cornersof the'sill formation will be" enertheside members of the window frame, the

frame thus being formed upside downi Itmust be evident, especiallywhen'ithe side vertical membersextend upwardly only a limited. distance,that the window frame structure can readily be formed upout'ffof r aflat sheetof metal instead of out ofianb I g s0- If desired the sidemembers of the window angle section,

frame pressing need only extend upwardly a limited distanceto preservethe advantages of the sill orst'ool formation. Theseadvantages consistnot only in, the "provision of a much'strongerrwmdow frame, but also 1nthe' ehminatlon of rust and consequent'deterioration at the 7 bottomcorners of the usualbuilt upcar window openings formed byover-lapping orabutting members which open up, particularly. under the movement ofthecar, which causes the paint to break trance ofmoisture.

To a substantial extent the advant'a g es of this window frame structurewould still be 7 at such points,itherebyrpermitting the err-,

preserved even if'fthe' side flanges of the 7 vertical members wereomitted; 'It'should therefore be understood that I do not limit thescope of thi's'invention to the details of construction shown; v v I Inorder that the invention may be readily understood preferred andmodifiedembodiments of the same are set 'forthin-the ac companying drawings andinthe description based thereon, it being understood that the drawingsanddes'cription' are to be taken n an illustrative rather than in an11nneces sarily limiting sense, 7 In the drawings.

Fig. 10 is a vertical section through the lower portion of a windowshowing the formation of the window sill in its relation to the sash andto the belt rail of the car;

Fig. 11 is a horizontal section on the line 1111 of Fig. 10;

Fig. 12 is a diagrammatic View illustrating the method of forming thewindow frame; 7

Fig. 13 is a horizontal section through one of the side members of aslightly modified form; and

Figs. 14 and 15 are detail vertical sections through the upper portionof the lintel and sash showing the insertion of a filler block andweather strip.

In the drawings the window frame is shown as comprising the horizontalsill or stool portion 21-21 and the upright side frame members 22 formedintegral therewith and the junction therebetween generously filleted inthe angle as indicated at 23. The upper ends of the side members 22 aretied together by means of the letter-board 24:

either directly by being riveted thereto as illustrated in Fig. 3 orindirectly by the interposition therebetween of a finish member 25, thelintel of the window being formed in the one case by an inwardlydeflected portion as of the letter-board itself, or by the deflectedportion 25 of the finish member. Preferably the window frame is dividedcentrally by a vertical window post 26 which is connected to the letterboard as showin in Figs. 3 and 9 according as to whether the lmtel ofthe window and post is formed by the deflected portion of the letterboard or finish member. The lower end of the post rests upon the silland is connected thereto as indicated in Fig. 4 by means of a fillermember 27 disposed within the hollow post and secured to the sill as bywelding or riveting as indicated at 28 and to the front wall of the postby means of the rivets 29.

To form the connection between the side members 22 of the window frameand the letter-board at the upper corners of the frame the front face 22of the side frame is preferably extended upwardly behind theletter-board and riveted thereto as indicated at 30. Where the finishmember 25 is employed it may terminate at and abut against the sidemember 22, as indicated in Figs. 5 and 6, or it may extend beyond thelatter as indicated in Figs. 7 and 8, and a portion of the rivets 30 maypass through the three members 22, 24c, 25, (Fig. 8).

Above the lintel, indicated at 24; and 25, a filler block 31 may beinserted carrying a weather strip 32 bearing against the sash member 33,as indicated in Figs. 1 1 and 15.

The window frame in the course of production is formed by an angle beamindicated in dotted lines at 34 in Fig. 12, said beam being shown as ofL-formation with a flange 35,, although a different cross section may beemployed depending upon the conformation of the frame desired to beproduced.

Heretofore it has been usual where car window frames are composed ofintegrally formed members to blank out for the window opening and forthe movement of the sash, making an expensive operation of many stepsand resulting in great waste of the material blanked out. I simplify theoperation and save waste by forming the window frame from an angle beamin the pressing die acting upon the material transversely of its lengthto fold the same into a U -shape, the bottom of the U constituting thesill and the vertical portion of the U constituting the upright sidemembers of the frame. in the pressing of the frame die members areemployed having such a conformation as to produce the step 21 andstraighten the'fiange to form a forward extension 21 of the sill, saidfiangc retaining its shape at the sides to form the face plate 22 of theside frame members. The lines of junction between the sill and sideframe members are generously filleted as previously stated so as toobviate any sharp angles.

The dies may be so formed as to bend the material inwardly as indicatedat 36 in Fig. 13 to form an integral window stop where desired.

The portion 21 of the sill and the forward extension 21 overlie the beltrail 37 of the car and the overlapping portions of the various parts areprotected from the entrance of moisture by means of a finishing sheet 38which not only overlies the face plate 22 and the sill extension 21",but also is downturned as indicated at 39 in Fig. 10 so as to seal thedivision line and the space which would otherwise appear between thesaid sheet and the car side between the successive window frames.

It should be noted that not only are the longitudinal and transverseangular bends of the sill and the side members very generously filletedbut that the corners formed by the sill and side members are also wellfilleted, as shown at 21.

Also it should be observed thatthe front face of the central uprightmember 26 lies back of the plane of the front faces of side members 22,the said member 26 being curved or filleted at its lower and upper endsas shown at 26 and 26*.

Attention is also drawn, as shown in Fig. 11, to theinserting of theside members 22 into the post construction of the car, whereby flushguide surfaces for the edges of the sash are obtained, even if the saidside members extended upwardly only a limited distance.

I claim:
